Description

  The present invention relates to a system for automatically testing and / or measuring a plurality of substantially identical parts with X-rays, the system comprising a test device having a support and a continuous rotation on the support. Automatically mounted rotor, X-ray device arranged on the rotor, protective enclosure surrounding the test device, handling device for operating parts during the test, and system automatically A control / evaluation unit configured to control and evaluate the X-ray signal by computer tomography. The invention also relates to a method of operating such a system.

  This type of system is used, for example, in automated continuous testing of casting (in-line testing) in situations where the device is integrated into the manufacturer's production line.

  A system of the type mentioned in the introduction is known, for example from EP 2278305A1. The parts to be tested are pushed linearly through the rotor by a belt conveyor extending through the test apparatus. The cross-sectional dimensions of the parts to be tested are considerably limited by a number of boundary conditions. Firstly, the belt conveyor already occupies a part of the circular empty cross section of the test device, so that part can no longer be used for the part itself. Secondly, the belt conveyor must have a certain minimum width, and as a result, because of the circular empty cross section, the belt conveyor cannot be arranged in the lowest area of the empty cross section, Will also lose considerable height. As a result, only a small portion of the actual empty cross section of the test equipment is available for testing the part.

  It is an object of the present invention to provide a CT system and corresponding method suitable for in-line testing of parts that results in a test apparatus having the largest empty cross-section in the part being tested.

European Patent Application Publication No. 2278305

  The present invention achieves this object by means of the independent claims. According to the invention, the handling device is configured to reciprocate periodically between the loading area and the test area. This is therefore a handling device that reciprocates. According to the present invention, since the component can be accommodated in the general-purpose end face element of the handling device suitable for various accommodating / holding means adaptable to the component, the handling device according to the present invention includes a conveyor passing through the test device, In contrast, the entire empty cross section of the test device can be utilized for the part. As a result, the present invention allows testing of parts having a considerably larger cross-sectional area as compared to a conveyor that passes through a testing device. The test equipment has a specific cooling period that can be used after each test process without wasting time to unload the tested part and load the next part to be tested. Surprisingly, the test cycle is not extended by the present invention.

  Advantageously, the handling device is mounted on the side or test surface of the test device opposite the loading area. This eliminates the need for a structure for storing the handling device in the loading area, so that the entire structural space of the loading area is particularly available for devices for loading and unloading parts. This is advantageous. In addition, the handling device can advantageously be arranged substantially completely inside the radiation protection housing, i.e. fully protected. Due to this feature, the handling device according to the invention is different from a conventional patient table, for example for a medical CT system in which the table always places the patient on the side of the table base.

  The present invention is described below with reference to advantageous embodiments and accompanying figures.

  The system 10 controls the test / measurement device 11, in particular the handling device 60 for handling the part 12 during an X-ray test in the test / measurement device 11, controls the system 10 and evaluates the X-ray signal by computer tomography. In order to shield the environment from the X-rays generated by the electronic control / evaluation unit 14 and the X-ray tube 24, specifically, for example, by an X-ray absorbing layer containing lead, And a protective enclosure 15 surrounding the test / measurement device 11. The programmable or programmed control / evaluation unit 14 is generally arranged in an operating area 67 outside the radiation protection enclosure 15 and comprises, for example, an operating terminal 88.

  The test / measurement device 11 comprises a support 17 and an annular rotor 18 which are stationary during the test. The support 17 includes a base frame 19 that is firmly fixed to the ground plate 23. The annular part of the support 17 forms the annular rotary bearing of the rotor 18. The ring unit 16 formed by the rotary bearing, the rotor 18 and the annular part of the support 17 is provided with a central ring opening 26 for displacing the part 12 through the ring unit 16 during the test (see FIG. 7). Wanna) In order to allow horizontal orientation, the ring unit 16 can be inclined with respect to the base frame 19 by a horizontal pivot bearing, for example in the range of ± 30 °. The part 12 is conveyed through the rotor 18, preferably parallel in the axial direction, i.e. parallel to the rotor axis.

  The X-ray tube 24 and the X-ray detector 25 are mounted on the rotor 18 on the opposite sides from each other. As can be seen in FIGS. 5 to 7, the X-ray tube 24, preferably configured as a rotating anode tube, is preferably configured to generate a fan beam (20). Alternatively, the x-ray tube 24 may be a cone beam type. Conveniently, the x-ray tube 24 is configured to illuminate the entire detector 25 with x-rays 20, and therefore comprises a beam angle of preferably at least 40 °, preferably at least 60 ° in one direction. In order to obtain sub-millimeter resolution, the focal size of the X-ray beam is preferably less than 1 mm, more preferably less than 0.7 mm. The x-ray tube 24 is preferably operated with an energy of at least 80 kV, more preferably at least 100 kV, more preferably at least 120 kV, for example about 140 kV. For the purpose of favorable high penetration capacity, higher X-ray energies up to 450 kV are conceivable. To reduce test time or measurement time, the x-ray tube 24 is preferably operated with a continuous power output of at least 1 kW. In order to prevent problems due to excessive heat generation, the continuous power output is preferably less than 10 kW. In one embodiment not shown, only the x-ray tube 24 is attached to the rotor 18 and a stationary detector 25 forms a 360 ° ring.

  Specifically, the X-ray detector 25 is a semiconductor detector, preferably a digital type that directly converts incident X-rays into electrical count pulses. The X-ray detector 25 is preferably a line detector, and preferably has at least 16 parallel lines. The X-ray detector 25 preferably has a sufficient length so as to obtain the largest possible angular range of the X-rays emitted by the X-ray tube 24. The X-ray detector 25 is preferably bent in a banana shape so that it has a substantially constant distance from the source point of the X-ray tube 24 throughout the sensitive surface. 5 to 7, the banana-shaped detector 25 is cut here so that only the end of the detector 25 is visible. In order to obtain an image resolution of submillimeters, the pixel size of the detector 25 is at most 1 mm, preferably at most 0.7 mm.

  During the X-ray test of the part 12, the rotor 18 is continuously rotated around the central longitudinal axis of the ring unit 16 by a rotary drive mechanism (not shown) attached to the support 17, and for each part 12. Thus, the rotor 18 performs a complete rotation of 360 ° a plurality of times. The X-ray tube 24 that rotates together with the rotor 18 and the X-ray detector 25 is supplied with power by a high voltage supply unit 79 using a slip ring assembly disposed between the rotor 18 and the support 17. The axis of rotation of the rotor 18, ie the longitudinal axis of the ring unit 16, is preferably oriented parallel, preferably substantially horizontally, to the direction of movement of the part 12 through the test / measurement device 11.

  For example, the system 10 is arranged on a conveying device 13 such as a roller or a belt conveyor so as to continuously supply and remove a plurality of substantially identical parts 12 to be tested. The conveying device 13 is preferably configured as a conveying line, ie a linear conveyor, and can be part of a production line, for example.

  The system 10 comprises, for example, a loading device 22 which in this case is configured as a robot. Other embodiments of the loading device 22 are possible. The loading device 22 takes in the component 12 to be tested from the conveyor 13, transports it to the handling device 60 for testing (loads it on the testing device 11), and acquires the component 12 from the handling device 60 after the test (testing device). 11 is unloaded) and acts on the conveyor 13 for transportation. In particular, when the handling device 60 itself is configured to detach the component 12 from the transport device 13, the loading device 22 can be omitted. The handling device 60 can also detach the component 12 in another way, for example manually.

  In order to insert and remove the part 12 with respect to the protective enclosure 15, the protective enclosure 15 is provided with a loading opening 39, which is used during X-ray tests so that protection against radiation is always guaranteed. Can be sealed in a radiation-proof manner, for example by a slider (not shown).

  In particular, the tube 43 is guided through the rotor 18 to protect the test apparatus 11 and the ring unit 16 not only from contamination due to the introduction of the part 12 but also from damage due to incorrect placement of the part 12, for example. It is burned. The tube 43 defines a transport tunnel for the part 12 to be tested. The tube 43 preferably extends from the loading opening 39 through the test device 11, i.e. through the ring opening 26 of the ring unit 16, over the test device 11 by a minimum length, which is the minimum length of the tube 43. It is defined by the plate 64 still in the tube 43 in the fully retracted position (see FIG. 3). For example, the tube 43 can protrude on the test apparatus 11 by an equal distance in both directions, i.e. it is arranged symmetrically with respect to the test surface E, for example as shown in FIG. In this case, the test surface E is a surface that extends perpendicularly to the rotor shaft 18 through the X-ray, ie, has a maximum X-ray intensity. The diameter of the tube 43 is advantageously adapted to the inner diameter of the ring unit 16 so that the largest possible part 12 can be tested.

  Preferably, the tube 43 is attached to the housing 15 at its front end, ie in the region of the loading opening 39. Therefore, the loading side opening of the tube 43 advantageously forms a loading opening 39 in the housing 15. Preferably, the tube 43 is connected at its front end to the housing 15 in an airtight manner, in particular using an annular sealing member 81 at the end defining the loading opening 39. The tube 43 can be held, for example, on the base 68 at its rear end, for example by a support 75 attached to the base 68.

  The tube 43 is radiolucent at least in the area exposed to X-rays. Preferably, the tube 43 is assembled from a central radiolucent part 73 in the X-ray region and several parts, such as one or more, in particular two, parts 74 outside the X-ray region. Thus, the latter need not be configured to be radiolucent and can therefore be made more robust from less expensive materials. Specifically, the pipe portion 74 can be configured as a half shell for the purpose of better dismantling for maintenance, for example. The tube 43 preferably has no openings in the tube wall so that no dirt particles can enter the test / measurement device 11 from the part 12.

  Advantageously, the handling device 60 should be tested, in particular for handling the part 12 during an X-ray test in the test / measurement device 11 and for returning the part 12 from the test area to the loading (unloading) area 61. The part 12 serves to transport the part 12 from the loading area 61 arranged outside the radiation protection housing 15 and before the loading opening 39 to the testing area in the test / measurement device 11. In other words, both loading of the part 12 to be tested into the handling device 60 and unloading of the handling device 60 takes place in the same loading area 61, i.e. advantageously on the same side or test surface E of the testing device 11. Is called.

  The handling device 60 includes a base 68 that is stationary on the floor, such as a base frame (see FIG. 3), and a displacement unit 69 that is axially displaceable on the base 68. Within the context of the present application, the axial direction relates to the axis of the rotor 18. Advantageously, the base 68 is mounted on the side of the test device 11 or the test surface E opposite to the loading area 61, preferably in the radiation protection housing 15. The displacement unit 69 comprises at least one, preferably a plurality, in this case two linear reciprocating elements 70, 71 which can be displaced relative to one another. Specifically, the first linear reciprocating element 70 is axially displaceably mounted on the base 68, and the other linear reciprocating element 71 is axially disposed on the first linear reciprocating element 70. It is mounted so that it can be displaced. Therefore, the length of the displacement unit 69 can be changed in an expanding and contracting manner. The axial displacement possibility of the linear reciprocating elements 70, 71 can be realized specifically by the corresponding linear guide.

  Advantageously, by using a plurality of linear reciprocating elements 70, 71, the function of transporting the part 12 between the loading area 61 and the test area is the function of displacing the part 12 through the test area during the X-ray test. Can be separated from Specifically, the displacement of the linear reciprocating element 71 relative to the linear reciprocating element 70 causes the component 12 to be displaced relatively slowly, albeit with high accuracy, in the test / measurement device 11 during the X-ray test. be able to. By displacing the linear reciprocating element 70 with respect to the base 68, for example, the part 12 to be tested is transported from the loading area 61 to the testing area 78 or returned from the testing area 78 to the loading (unloading) area 61. Can be. This transportation does not have to be the same high speed and can therefore be performed at a higher speed using a less expensive drive.

  In order to obtain sub-millimeter resolution, the handling device 60 advantageously advantageously feeds the part 12 through the test area 78 at a substantially constant feed rate, i.e. with a feed rate variation of less than 10%, preferably less than 5%. And more preferably adapted to transport less than 1%. For this purpose, the linear guide between the linear reciprocating elements 70 and 71 preferably comprises a drive device, which preferably uses a linear motor or a servo motor to achieve the required stability in feed rate. And controlled with corresponding accuracy. After the above, the linear guide drive 34 between the linear reciprocating element 70 and the base 68 for transporting the part 12 before and after the X-ray test should provide the same high stability of speed. Therefore, it can be constructed without much cost.

  A vertically oriented plate 64 is attached to the end face of the displacement unit 69 facing the test device 11, in this case the end face of the linear reciprocating element 71. The shape of the plate 54 preferably corresponds to the shape of the empty cross section of the ring unit 16 or the tube 43. Thus, in the case of a tube 43 with a current (circular) round cross section, the plate 64 is also advantageously circular. Preferably, the outer diameter of the plate 64 is adapted to the inner diameter of the ring unit 16 or the tube 43. Thus, the plate 64 preferably fills the empty section of the rotor 18 or tube 43 substantially completely, except for the gap between the plate 54 and the tube 43, which is preferably an annular sealing member 80. Is sealed in a highly airtight manner.

  The workpiece 12 is disposed or held on the front side of the plate 64, i.e. on the side far from the base 68, facing the loading opening 39. For example, as is apparent from FIG. 3, the entire empty cross section of the ring unit 16 or tube 43 is generally available for the workpiece 12.

  Preferably, means for receiving or holding the workpiece 12 are provided at the front of the plate 64. This accommodating means or holding means can have various configurations. In the exemplary embodiment of these figures, this is, for example, support member 27, having a horizontal support surface 77 attached to plate 64, on which part 12 rests. Although the support member 27 takes up a certain space, the support member 27 and its arrangement, in particular the vertical arrangement, can be adapted to the part 12 to be tested, so that the part 12 to be tested is more than prior art. There is still a fairly large space available for. The shape of the support member 27 is variable.

  Alternatively, the receiving means or holding means may be, for example, a clamp holder, a gripping tool, a device for hooking the part 12 on the plate 64, a container with an open top to insert the part 12, a plurality arranged at the same level Or the like, all of which can be provided, attached, or attached to the front of the plate 64. In this case, many variations are possible. Magnetic or electromagnetic adaptations, especially for ferromagnetic parts, for example the shape of the magnetic plate 64, are also conceivable. Advantageously, the containment / holding means can be adapted to the part 12 to be tested in each case. Accordingly, the receiving / holding means is preferably an adapter part. Moreover, the receiving / holding means can advantageously be removed from the plate 64 and replaced, for example, with another receiving / holding means. Advantageously, the receiving means or the holding means are substantially transparent to X-rays in order to minimize the influence on the imaging of the part 12.

  Preferably, the holding portion 27, or more generally the receiving / holding means, can be height adjustable. For this purpose, for example, an electric height adjusting device 63 is provided, which is preferably attached to the plate 64, specifically to its rear part. Specifically, the holding part 27 is guided so that it can be displaced vertically on the handling device 60 or the plate 64. The height adjusting device 63 includes, for example, one or a plurality of vertically arranged linear guides 65 and an electric drive mechanism 66 in addition to the corresponding gear unit. The holding part 27 can be adjusted in height so that it can be fitted to a part 12 having, for example, various dimensions, so that the part 12 passes through substantially the center of the ring unit 16. obtain.

  Moreover, the height-adjustable holding part 27 can optionally act as a loading device 22. For example, the lowered holding portion 27 can move under the part 12 being fed on the conveyor. By lifting the holding part 27, the parts can be removed from the conveyor 13 and then tested. After the test, the holding part 27 with the part 12 moves onto the conveyor 13 and lowers so that the part 12 is placed on the conveyor and carried away.

  In general, the containment / holding means may advantageously be rotatable and / or displaceable relative to the plate 64 about one or more axes. For example, the containment / holding means can advantageously be displaced along the axis of the rotor 18 or can be extended or retracted, for example to obtain a sufficient reach to load / unload the conveyor 13 The length can be adjusted with. In that case, another loading device 22 is probably unnecessary.

  In accordance with the present invention, the maximum structural space is also available on the rear of the plate 64, ie on the side of the base 68 away from the loading opening 39. For this purpose, the linear reciprocating element 71 can, for example, be advantageously constructed very robustly. This is evident, for example, from FIG. 4, where the linear reciprocating element 71 is preferably in the form of a double U-section with adjacent base legs. In particular, if the linear reciprocating element 71 is advantageously airfoil, there is also a lot of space at the rear of the plate 64, for example for the height adjustment device 63 and other functional devices.

  The progress of the test process is as follows. For example, the part 12 to be tested is removed from the conveyor 13 by the loading device 22 and placed on the support member 27 of the handling device 60 or more generally passed to the handling device 60. At this point, the handling device 60 is in the loading position and the displacement unit 69 is maximally displaced towards the loading area 61 so that the area in front of the plate 64 in which the parts are to be placed (i.e. receiving / holding means, In this case, it is in the support member 27) and outside the protective enclosure 15. Specifically, the end of the plate 64 is at approximately the same height as the front end of the tube 64 in this position, which is shown in FIGS.

  Then, by displacing the linear reciprocating element 70 or the entire displacement unit 69, the plate 64 with the part 12 is pulled back along the base 68 until the part 12 almost reaches X-rays. Next, the displacement of the linear reciprocating element 70 or the displacement unit 69 is stopped, and the transportation of the parts to the test area 78 is completed.

  The plate 64 is then further pulled back with the part 12 by displacing the linear reciprocating element 71 along the linear reciprocating element 70 at a highly constant but possibly low speed, so that the test area 78 is drawn. The part 12 moves through the X-ray 20 and an X-ray image is obtained. FIG. 6 shows a time point during the X-ray test.

  When the part 12 exits the X-ray beam 20 or the test area 78, the displacement of the linear reciprocating element 71 is stopped and the X-ray test of the part is completed. This point is shown in FIG. Here, the handling device 60 is pulled back at the highest speed.

  The plate 64 then displaces the part 12 by displacing the linear reciprocating element 70 or the entire displacement unit 69 at an increased transfer rate until the unloading condition shown in FIGS. 1, 2 and 5 is reached. Along with this, it is pushed out along the base 68. Since the plate 64 is advantageously sealed against the tube 43 by an annular seal 80, the plate 64 advantageously projects potential dirt from the tube 43 after each test process. For example, the tested part 12 is removed from the handling device 60 by the loading device 22 and placed on the conveyor 13 for transport to another location, and the next component 12 to be tested is supplied.

  During the test, the part 12 to be tested is displaced in translation along the axis of rotation of the rotor 18 by the test / measurement device 11, and at the same time the X-ray systems 24, 25 are continuous around the part 12 to be tested. The overall result is that the x-ray systems 24, 25 move in a spiral around the part 12 to be tested. During the X-ray examination, no rotation of the part 12, in particular rotation around the longitudinal axis, or displacement around another axis occurs. There is no need for a further manipulator for the part 12, such as a rotary table.

  The control / evaluation unit 14 comprises a fast CT reconstruction algorithm for converting the X-ray data recorded from the helical dimensions into a volume or voxel representation. Moreover, the control / evaluation unit 14 comprises an algorithm for analyzing the volume image depending on the intended use. By evaluating the X-ray signal with computer tomography, information about the three-dimensional internal structure of the part can be obtained in a manner known per se, for example the exact position and shape of the casting gas cavity. Specifically, this is an internal material defect or anomaly determined by a given test parameter, such as gas cavities, porosity, and the substantially uniform material of the part 12 contains a higher concentration of material. Can be automatic detection. Each part can optionally be categorized as “normal” or “abnormal” and can optionally be visually marked accordingly or automatically discarded. Finally, the control / evaluation unit 14 can comprise a communication unit for exchanging data with an external unit, for example a central controller of the production system. Using system 10, automatic continuous inspection of parts 12 can be performed in a short time that is compatible with the cycle time of the production line.

  In addition to or instead of the helical scan mode, the control / evaluation unit 14 performs an axial scan and / or a scan of only a part of the part 12, for example an individual disk, or a scan at a specific position. can do.

  Instead of, or in addition to, detecting internal defects or anomalies in the part 12, the control / evaluation unit 14 determines from the X-ray data the three-dimensional geometric dimension of the part 12, i.e. the internal and external part structures. Can be configured. In that case, another coordinate measuring device can optionally be omitted.

  In order to compensate for the hardening effect of the X-ray beam, the corrections that are advantageously performed in the control / evaluation unit 14 are adapted to the inspection of common materials such as metals, alloys, composites, aluminum, iron, etc. .

  The system 10 is demarcated for baggage inspection devices that must adapt the assessment to an exceptional spectrum of the contents of a particular baggage. In contrast, an apparatus according to the invention for inspecting a plurality of substantially identical parts fits a part to be tested, or a limited number of part type mixtures, in a convenient manner. Can be done. These devices are therefore made quite different, especially with respect to X-ray parameters and evaluation algorithms. Preferably, the system is configured to obtain a volume resolution of X-ray images of 1 mm or less. In view of this fact, the present invention can basically delimit a baggage check device that functions at a resolution of several millimeters.

  The device according to the invention can be used for material testing (metrology) to measure internal and external part structures in addition or instead. In that case, another coordinate measuring device can optionally be omitted.

  In order to prevent dust or moisture from entering the protective enclosure 15, the protective enclosure 15 is preferably completely closed or sealed, with the exception of possible temperature adjustment openings, for example. This is advantageously done by sealing the tube 43 against the housing 15 in the region of the mounting opening 39, in particular by the annular seal 81, and in particular by the annular seal 80, with the plate 64 against the tube 43. This is done by sealing. Thus, the test / measurement device 11 is arranged substantially encapsulated in the protective enclosure 15.

  In order to dissipate the heat generated during the operation of the test / measurement device 11 and keep the interior of the protective enclosure 15 at a sufficiently low operating temperature, even in very warm environments such as a manufacturing plant, a temperature control, for example an air conditioning system. The cooled cooling unit, specifically, the electric cooling unit is attached to the protective enclosure 15. In the case of possible leaks and through possible functional openings such as the exhaust opening of the air conditioning system, preferably the enclosure 15 is overloaded so that no dust or moisture can enter the protective enclosure 15. A device for pressing is provided. For example, this can be a compressed air connection that can be connected to an external compressed air source via a compressed air line. Alternatively, overpressurization can also be performed by a cooling unit.
